lM PROVEM ENT lN TOOL-HANDLES.

Specification forming part of Letters Patent No. 195,739, dated October 2, 1877; application filed August 18, 1877.

To all whom it-may concern:

Be it known that I, JOHN HoPKINs AN- THONY, of Oamanche, in the county of Clinton and State of Iowa, have invented a new and useful Improvement in Fastenings for Tool- Handles, of which the following isa specification:

Figure 1 is a front view of a fork to which my improved fastenings have been applied, the upper screwferrule being shown in section, and part being broken away to show the construction. Fig. 2 is a detail sectional view of the lower part of the fastening.

Similar letters of reference indicate corre sponding parts.

The object of this invention is to furnish improved fastenings for securing tools or handpieces to handles, which shall be so constructed as to enable the said tools or hand-pieces to be applied to new handles easily and quickly, so as to avoid loss of time and expense, and which shall hold the said tools and handpieces firmly and securely.

The invention will first be described in connection with the drawing, and then pointed out in the claim.

verse grooves are cut in the inner ends of said flattened parts. The pieces or clamps 'G are then applied to said flattened places, as shown in Figs. 1 and 2. The inner sides of the clamps O are flat, their inner ends have inwardly-projectin g flanges formed upon them, and their outer sides'are rounded off to correspond with the surface of the handle B. Upon the outer surface of the clamps O and handle B is cut a screw -thread, to receive the threads of the screw-ferrule D, the outer surface of which should have flanges, lugs, or projections formed upon it, to enable it to be grasped and turned by a wrench.

In the case of hand-pieces E and of some tools, the clamps C may be formed upon the said hand-pieces and tools, and may be then applied to the flattened sides of the handle, as shown in the upper part of Fig. 1, and socured in place by screw-ferrules, as hereinbefore described.

When the clamps G are separate their outer ends should be so formed as to grasp the head of the tool, as shown in Fig. 2.

With this construction, by screwing the screw-ferrule D inward upon the handle B until the clamps O are uncovered, the tool and handle can be readily separated, so that the tool may be readily supplied with a new handle.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination, with the ferrule D, of the handle B, longitudinally flattened and transversely grooved at upper end, and the clamp O, flattened and flanged on the inside, as and for the purpose specified.
